The present research investigates the torsional aeroelasticity of the blade of an H-type vertical axis wind turbine subject to stall and post-stall conditions in various Reynolds regimes, which is experienced by the blade in a full revolution. In order to simulate the aerodynamics, a new model based on a combination of the Double Multi Streamtubes (DMST) model and the nonlinear multi-criteria C...

BACKGROUND There are two forms of Macintosh laryngoscope blade. Compared with the standard blade, the English blade is longer, its curve is more continuous across the entire length of the blade, the flange of the blade continues much closer to the blade tip, and the height of the flange is shorter. METHOD We studied 300 patients to compare the ease of laryngoscopy with each type of Macintosh ...

ACKNOWLEGMENTS First and foremost, I would like to thank my advisor, Prof. Ali Adibi, for his support and guidance throughout my PhD years, and for giving me the chance to be a part of the Georgia Tech community. the past six years. for their kind efforts in reviewing the present dissertation, and for honoring me with their presence at my doctoral defense session. especially Devin Brown and Gar...

LEAVES OF CERTAIN ferns are commonly cited as "primitive" on the general theory that they have retained dichotomy of the major vascular axes of the leaf from ancient psilophyte ancestors (Zimmermann, in Verdoorn, 1938; Lam, 1948). The present study suggests a re-interpretation to be based on comparisons with ordinary fern leaves, "pinnate" in the arrangement of their main veins. The term "folia...

The Savonius wind turbine is a type of vertical axis wind turbine (VAWTs) that is simply composed of two or three arc-type blades which can generate power even under poor wind conditions. A modified Savonius wind turbine with novel blade shapes is introduced with the aim of increasing the power coefficient of the turbine. The effect of blade fullness, which is a main shape parameter of the blad...

Turbodrill is a type of hydraulic axial turbomachinery which has a multistage blade consisting of stators and rotors. In this paper, a turbodrill blade that can be applied in crystallized section under high temperature and pressure conditions is developed. On the basis of Euler equations, the law of energy transfer is analyzed and the output characteristics of turbodrill blade are proposed. Mor...

We applied an Iteratively Reweighted Least Squares (IRLS) approach to create a map of the Sea of Galilee. We use a bank of Prediction Error Filters (PEFs) as a residual whitener to reduce the acquisition footprint and map artifacts caused by non-Gaussian noise in the data.
